Granted, I live in a smaller city, but Minneapolis is about the same cost, unless you need to go a great distance for work. Just outside of DC is also about the same. A nicer home, car, and children are not necessities. As an adult, I spent 10 years working for less than $10\hr. A large number of people I know make less than $10\hr. In fact, I made less than $8\hr until I was 26, and I was still able to live rather comfortably because I didn't waste money on things that I didn't need.
Does this mean that I think things are fine? No, I agree that income disparity is a horrible problem in a country where the "average" income is $75k\year, but very few of us know anyone who makes that much money.
